PROBLEM TO BE SOLVED: To obtain a mounting frame the cost of which is lowered and which can comply easily with a case in which approval of a customer is slow by a method, wherein the mounting frame is constituted in such a way that long holes which are long in respective long directions are formed in a row in the respective long directions on two opposite sides in frame materials whose cross section is U-shaped, such that the frame materials are combined to be at right angles. SOLUTION: One pair of frame materials 1 are placed in the depth direction of a switchboard, so as to be at right angles to a pair of transversal direction frame materials 1. In this case, two opposite sides are situated in the upper part and the lower part, the interval between the depth direction frame materials 1 is set at a width wise direction interval required for mounting a housing device for a capacitor or the like. At this time, at points of intersection of the frame materials 1, bolts 4 are inserted into and passed through lower-side long holes 1a in the upper-side frame materials 1 and upper-side long holes 1a in the lower-side frame materials 1, nuts 5 are tightened to the bolts 4, the upper and lower frame materials 1 are fixed in four places, and a parallel crosses-shaped mounting frame is constituted. Then, the housing device is mounted by using a bolt and a nut on the upper-side frame materials 1 at the mounting frame by making use of the long holes 1a. |
